System Overview
A multiple channel system consists of two to four LT-82 transmitters and one or more radiators. The diagram

transmitter. This power supply can supply enough power for the LT-82 and two LA-140 radiators. If you need
more than two radiators, you can use the power from the other transmitters. In this example, the four
transmitter power supplies can supply enough power for up to eight LA-140 radiators. This is discussed later in
this document. Power issupplied from standard CAT-5 cable while RF from the transmitter is delivered using
50-ohm RG-58 coaxial cable. Each radiator is supplied with 25 feet (7.6 meters) of CAT-5 and RG-58 coaxial
cable.
Multiple Channel System
Up to four LT-82 transmitters can
be daisy chained together (using
RG-58 cable) to create a
multi-channel system

Interconnection Cable (included)
RF – RG-58 50 ohm Cable
RF – RG-58 50 ohm Cable
Up to 100 LA-140 radiators can be daisy chained
together (using RG-58 cable) to provide sucient
IR power for most applications

LR-44 IR Lanyard Receiver
Radiator Power: Radiators can be
powered from the LT-82 (up to two
radiators) or an additional power supply
(LA-205) can power up to two radiators
Radiator RF: RF from the last LT-82 must be
daisy chained from radiator to radiator
